Abstract
An integrator circuit is provided in the present invention, which utilizes a first capacitor and a first switching unit to sample an input signal and carries out distribution of charges between the first capacitor and a second capacitor. The second capacitor is larger than the first capacitor in capacitance. The integrator circuit transmits the charges stored in the second capacitor to a node of the first capacitor which is coupled to a ground previously. Accordingly, a direct current voltage level of the first capacitor may increase, facilitating an increase in a direct current voltage level at the second capacitor. Thereby, the accuracy and linearity of the integrator circuit may improve.
Claims10
An integrator circuit, comprising:
- a first energy storage component, coupled between a first node and a second node;
- a first switching unit, coupled to the first node, an input terminal, the second node, and a ground terminal, for selectively electrically connecting the first node to the input terminal and selectively electrically connecting the second node to the ground terminal;
- a second switching unit, coupled to the first node, the second node, and a third node, for selectively electrically connecting the first node to the third node and selectively transmitting a voltage at the third node to the second node;
- and
- a second energy storage component coupled between the third node and the ground terminal.
